Specification of Letters Patent.

Patented Dec. 8 1, 1 907.

Application filed March 6.1907. Serial No. 360.900.

To all whom it may concern:

Be it known that I, WILLIAM N. PARKES, a citizen of the United States, residing in Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Scalloping-Embroidery Machines, of which the following is-a description.

This invention is primarily intended for use in a machine in which the needle has a lateral movement such as is shown, and described in United States Patent Number 592,:510 issued to-me October 26, 1897. In the machine therein shown a needle is reciprocated vertically and vibrated or moved laterally, and the working position of the said laterally vibrating needle is automatically changed laterally.

In my present machine the needle or needlesare vibrated or moved laterally, and the position of the said laterally moving needles are changed laterally, but means other than those shown in my said patent are provided for performing these functions. In my present machine as in my said "previous-patent, the Working position of the laterally moving needle is changed laterally from the action of a cam which may be of any suitable shape. For example by using such a earn as is indicated in dotted lines in Figure 1, scallops as shown in Fig. 21 may be embroidered. In embroidering these scallops the work is moved along progressively as in a plain stitch machine, and simultaneously with this movement of the work, the-working position of the laterally moving needle is cam, and the embroidery stitches are thereby located along a scalloped path as shown in said Fig. 21. By referring to said figure it will be seen that, if the work is not moved laterally the working position of the laterally movin needle must change. progressively laterally all the time inorder to embroider a scallop as shown in said figure.

One of the main objects of my present invention is to provide means for cotiperating with a needle having a lateral movement such as described, for making a purl or but ton-hole finish along the edge of the embroidered scallop or design. And it-is also one of e main objects to provide means,for cooperating with a needlehaving sucha lateral place a filling material or cord under the said scalloped design.

In the work done on sewing machines the the action of saidthread is anchored in the material at the point w here the needle penetrates the same, and the thread runs on the surface of the material from one to another of these points as the stitchin progresses. When the needle is reciprocate only, and the work is moved in aright line only, the thread runs from one to another of said points in substantially a straight line, but when the reciprocating needle is moved laterally, then the said thread runs laterally to the lateral points where the needle penetrates the work.

A sewing machine is said to have made a stitch when the stitch-forming mechanism has anchored the thread in the material at the point where the needle previously penetrated the same. For the purpose of clearness in this application the portion of the needle thread that runs from-one to another of these stitches is called a link of thread, and the stitches are said to be connected on the top of the work by links of needle threads.

In a large number of different kinds of sewingniachines a relative lateral movement is the work, and this movement is subdivided into different kinds of specific lateral move- 'ments. For example a relativemovement alternately in opposite directions is produced and this is called a vibratory, oscillatory jogging, 'to and fro etc., relative movement. This movement consists of a single step in. one direction, and then a single step in the opposite direction. I11 addition to this movement there is what is called a progressive relative lateral movement. In this movement there, are a plurality of succesjsively relative lateral movements in one direction, and then a plurality of such move ments in an opposite direction.

The term, a relative step by step, lateral movement between said work,"used in this specification and the claims is to be understood to mean a plurality of relative lateral movements between the needle and thework in one direction during theinaking of a plurality of stitches, and then a plurality of relative lateral movements in an o posite direction during the making of a pl urality of'stitches and so on. And the term relative progressive stepby step, lateral movement means the same thing as saidrelative step b step lateral movement. Both of these terms mean a relative lateral movement in one direction during the makmg of a plurality of stitches, and then the produced between the needle or needles and needle and the" LOO 7 simultaneously therewith the laterally vibrat-- reversal of this relative movement during the making of another plurality of stitches. A progressive movement is to be understood to mean a movement in asingle direction during the making of a plurality of stitches in contradistinction to a to and-fro, or reciprocating movement.

It is common in sewing 'machines to pass back and forth under a needle, or under needles, an auxiliary thread, and for this purpose a laterally moving'fingei" is used. The device used in my invention for manipulating an auxiliary thread or cord is not to be understood to be a finger. By my device the thread is looped completely aroundthe links of the needle thread incontradistinction to simply passing the same under said links and thereby causing it to be stitched to the fabric. By my device the auxiliary'thread is I turned back and completely around the links of needle-thread as is clearly illustrated in the drawings. And this work is done and ing needle or needles, and the auxiliary co-- o erate the same acting parts are moved laterally and scallops with a purl or'i button-hole finish along their edge are thereby embroidered, and said purl is composed of said auxiliary thread and the needle-thread.

Referring again'to the objects of my present invention, it is noted that another im-' portant object of the same is, to provide means for loopin an auxiliary thread around links of the need e thread ofa laterally moving needle, and in line with one row of the lateral stitches. And it is also one of the important objects to so locate said ineans, and

t read may be looped or twisted around said auxiliary thread in line with one row of lateral stitches.

needle may uxiliary cord or tape guideddatthread or cord passedback and forth under said needle so that it is stitched'down on top of said first auxiliary cord.

Still another object so construct and locate needles may be movedlaterally step by step, an, auxiliary thread concatenated with the threads of said needles back and forth across the space between the'f same and a fill in 'material 'ded under-said auxiliary threa Other 0 "sets willib'e'i disclosed in connection with the illustrationgandthe'descrip tion of the same: Y

asshown in Fig. 5. The gear 17' has twice usual manner to the under side of the bed 1 of the machine. The gear wheel 7, is twice the diameter of thegear wheel 8, so it is to be understoodthat the shaft 9 revolves twice to each revolution of the shafts 4 and 5.

To the upper end of the shaft 9 is secured a hook 11, (which is adapted to carry a bobbin case and a bobbin,) to cooperate with the needle thread, and pass loops of the same around the said bobbin case, in substantially the same manner as described in-my United States Patent Number 730,692, dated June 9, 1903. In the said patent, the hook is arranged at the side of the needle for the purpose of doing plain stitching only, but in my application, Serial Number 93,037, filed F ebruary 7, 1902, the needles are arranged in front of the hook, and disposed so that they move laterally in a path that is concentric This disposition and construction of the looper as described in the said patent, and application, permits of a very large lateral movement of the reciprocating needleor, needles.

12 is a feed dog which is operated in the manner shown and described by me in application lt'umber 150,182, filed March 30, 1903, and the same may be removed from above the bobbin case in the manner shown in said l co-pending application.

While any suitable feed mechanism, and

in connection with my present invention, I prefer to use the feed mechanism shown in my said application, and the looper mechanism shown in my aforesaid patent and appli cation.

In bearings in the face of the arm of the machine, is located a needle-bar 13, to the lower end of which is connected a needle holder 14, which carries a needle 15. The needle-bar 13 is disposed so that the axis of the same is concentric with the axis of the looper 11, and the said needle-bar is reciprocated, and adapted to turn on its vertical axis, in the manner shown and described in the aforesaidco-pending application, Serial he needleis carried by the needle holder eccentrically with respect to the axis of the needle-bar, so that when the bar is oscillated, the needle is moved laterally in a' path that is concentric with the path of the beak of the looper-as before stated, and as described in the said co -pending application.

To the driving shaft of the machine issecured a gear 16, which meshes with a gear 17 the number of teeth as the gear 16, therefore the former turns only once to two revolutions of the driving shaft 1. A plate 18 which is secured to the arm of the machine by screws 19, and which has a portion 20 thatfextends in the arm of the. machine, 1 crank lever 36 is pivoted the lower end of a 13a serves as a bearing for a hub 21 formed on the gear 17, and a bearing plate 22 serves as a means for retaining the hub 21 inits bearing as shown in Fig. 5. A cam 23 is secured to the hub 21 of said gear, by means of a screw 24:,and the cam is rigidly held from turning relative to the hub 21 by means of a pin 25 that extends outwardly from the plate 22. It is now of course understood, that when the shaft 1 is revolved, the cam 23 is also revolved once to two revolutions of said shaft. On the upper part of the arm of the machine is secured a bracket 26, on which 'is formed bearing portions 27 and 28, and in the said bearing portions is located tooscillate shafts 29 and 30, which are disposed in a horizontal plane transversely of the arm of the machine.

Theforegoing is the means provided for driving the mechanism of my present invention, and the said means will be found more fully shown and described in my copending application Serial Number 179,470, filed November 2, 1903.

- I will now describe the mechanism which my presentinvention comprises, and which foregoing generally described mechanism.

is adapted for use in combination with the i It is desired that it be understood that my present invention may be used in combination with mechanism other than that described, and it is also to be understood that the preferred means herewith employed for be modified or changed in various ways.

It is understood of course, when the machine is in action the cam 23,v is revolved and this movement of said; cam'oscillates the part 33, the shaft 30and the segment arm or lever: 34. The cam is so constructed and timed,

that the said segment lever oscillates laterally when the needle is disengaged from the work, but has no lateral movement when the needle is in engagement with the work.

In the way 35 of the segment lever 34, is adjustably pivoted a bell crank lever 36 35. being shltwn in To the end of the short arm having' arms 36 and 37, the arm much shorter than the arm 37 as Figs. 1 and 4.

36 is pivoted one end of a pitman 38 comprising parts 38 and-39, these parts being adjustably secured together by means of a thumb nut 40 in the usual manner. forward end of the part 38 of the pitman is The secured at 41 (see Fig. 8) to an arm 42, and the latter in turn is secured to the needle bar 13. To the outer end of the arm 37 of the bell 105 the disclosure of my present invention may connection 43 comprising parts 43 and 44. Through the part 44 is formed a slot 45, and passing through said slot into a seat formed. in the part 43 is a thumb nut 46, by means of which, part 44 is secured to the part 43. The slot 45 permits the part 44 to be adjusted relative to the part 43, and the connection which comprises these two parts to be thereby made longer or shorter. The upper end of the said connection 44 is adjustably pivoted in a way 47 formed in the end 48 of a lever 48 -that is secured'to the forward end of-a shaft 49, the latter'being journaled in an auxiliarybracket 50 secured to the top of the bracket .26. The other end of said lever is forked as at 51.

A shoe 52 is suitably pivoted on the upper end of a slide- 53, and the said shoe is em braced by the forked end 51 of the aforesaid lever. The said slide is adapted to reciprocate in bearings 54 and 55, which are secured to theface of the bracket 26, (see Figs. 3 and 4.) shaft 56 is secured a ratchet wheel 57, in. the rear side of which is formed a cam roove 58, the path of which is formed as in icated by dotted lines in Fig. 3. slide 53 is pivoted an anti-friction roller 59 that extends into the 'cam groove 58 of the ratchet wheel, and by this means the slide is reciprocated when the ratchet wheel is rotated. On a hub 60 formed on the bracket 26. is pivoted an end 61 of a pawl lever 62,

which carries at its-outer endja pawl. 63 that engages the teeth ofthe ratchet wheel 57. Also to the outer end of said pawl lever, and in rear of the pawl, is pivoted one end of a connection 64, the other end of said connection being adjustably pivoted in away 65' formed in an arm 66, the latter being secured to the forward end of the shaft 29.

To the rear end of the shaft 49, is secured an arm 67 in which is formed a way 68, and in the said'way is adjustably pivoted a part 69 of a two part connection 69". vTo the lower end of the part 69 is adjustably secured by means of a thumb nut 70 the other part 71 of the said two part connection, a slot 72 being formed through the part 69 to permit of .he adjustment of the parts .of the said connection relative to each other; The

lower end of the part7]. is pivoted to't he' end of a part '73, andthe other end of said part 73' is adjustably secured in a curved way "7 4 formed in an arm 75 that is secured to the rear end ofshaft 30-. (See Figs. 4, 6 and 7); In the outerend of the part 73 'is'pivoted one end of a part 76, in the other end of said part.

76 is adjustably secured one end of a rod 77. To theother end of said rod is adjustably secured a bearing piece 78 which embraces a ball 7 9 secured to the outer end. of an arm 80. These parts 73, '76, 77 and 78 as a whole constitute a connection between the arm 75' and the ball 7 9 and I give the said connec- To the forward end of a short To the face of the tion reference character 78 This connection at 78 is joined so that a toggle joint is formed at this point in the same. end of the arm 80 is adjustably secured to the upperend of a small vertical shaft or red 81, by means of a screw 82 as shown in Fig. 8. The rod 81, is journaled-in-a tubular presser bar 83 which is mounted in a usualway in bearings in the face of the arm of the -machine.

The presser bar is adapted to be raised and the said bar is depressed by the usual presserbar spring as is shown in my co-pending application Serial Number 32,041, fi ed October 4,1900.

T o the lower end of the pressen'bar 83 is clamped'by meansof a screw 84 a presser foot carrier 85, and to the said carrier is secured by means of a screw 86 the shank 87 of a presser foot 88. (See Figs. 9, 10*and 11.) Just below the end of 'the presser bar is clamped to the lower end of the rod 81, by means of a screw. 89 a bearing 90 adapted to carry an auxiliary thread carrying finger or arm 91. The bearing 90 has a way 92 milled in it, and. in said'way is located a flattened end 93 of the finger 91, and'through said flat end a slot 94 is formed, through which passes a screw 95 that is seated in the said bearing 90'. The said way, slot and screw serves as a means for adjusting the finger 9l horizontally, and securing the same to the bearing 90. The finger or arm 91 extends in a curved manner from the bearing90, asjshown in Figs. 10, 11, 12 and 13, and has formed on it near its outer end a nose 96, through which runs a thread eye 97. From the point of the nose 96 run inclines 98 and 99. The incline 98 terminating in an end 100, as shown in the said figures, the object 'of this construction of the said finger 91 will be ex plained in connection with the workings of thejmachine. I In the upper side of the presser the needle slot .102.

depression is to permit the nose of the finger to operate close to the material, In the face of the. presser foot-88, back of the needle slot 102 ,is milled a way or groove'mot shown) that extends to the heel ofthe presser-foot,

suitable for the passage 'ofthe' embroidered scallop. or design as it is fed away from the needle.

On the top ofthe arm of/the machine, is

l secured another 'bracket 103, having an up.-

iournale'd a' short'shaft 105. To the forward end'o-f said shaft is secured a bell crank lever 106 in one arifi of which is formeda way 107, to the rear side of'the end 108 of the said lever is pivoted the lower end of a connection 109, the'upper end at said connection being ivoted to the rear side of the end 48 of the ever that isin engagement with the slide The other foot is a depression 101, through which passes The object of the said.

Wardlv extending portion" 104 in which is vlowered by a usual presser foot lifter, and

' and 3.

one end of a part 110, of a, two part connecs 53. The arm 108 of the bell crank lever is considerably longer than the other arm of the said bell crank lever as is shown in Figs. 1 In the way 107 is adjustably secured tionlll, and the other end of the part 110 is adjustably secured by means of a slot 112, and a screw 113, to one end of the-part'114 of the said two part connection, and the other end of said part 114, is'pivoted at 115 to the upper'end of a lever 116. A bracket 117 is secured to the arm of the machine, and on the same is pivoted at 118 the lever 116. The lower portion 119 (see Fig. 9) of the lever 116, is bored, and in the said bore is located a spring 120, and. a plunger 121. In the said plunger is secured a pin 122 that extends outwardly into a slot 123 formed through the wall of the lower portion of said lever, as shown in dotted lines in Fig. 9. The normal tendency of the spring 120 is to press the plunger downwardly and the pin f 122 coming in engagement with the lower end of'the slot 123 limits the downward movement of the said plunger and the engagement of the said pin with the lateral wall of the said slot prevents the plunger from turning laterally in its hearing. The lower end of the plunger is elbowed as shown in Fig. 9, and. from the elbow it terminates into a finger 124 that extends under the auxiliary thread carrying finger or arm 91., as shown in .Figs. 10,11, 12 and 13. At the heel (if the said 'elbowed portion commences a bore 125 that passes longitudinally through the finger 124, so that a filling material or .cord may enter the said bore at the heel of the elbow,- and be discharged from the finger at its extreme end 126.

It will be understood from the foregoing that when the presser-foot is elevated it will contact with the .under side of the finger 124 of the plunger 121 and raise the same against the action of the spring 120. It is thus seen thatmeans are rovided for raising the finger and auxiliary ooperwith the presser foot for the insertion or removal ofxthe work, or for other purposes.

Reference character 127 represents the needle thread when a single needle is used, and reference character 128 the thread of an additional needle.

carried bythe auxiliary thread carrying finger or arm 91, and reference character 130 represents a filling-material that is guided through the finger124 and reference character 131 represents the additional needle when more than one needle is used.

Reference character- 129 represents an auxiliary thread which is through the nose of the said finger.

finger moves laterally by the needle thread movement of the said connection and the parts operated by it. Then the'bell crank lever 36 is adjusted in the way 35 a sufiicient distance fromthe axis 'of the shaft 30 to produce the desired extent of lateral movement in the needle. Under this adjustment the bell crank lever 36 will be carried bodily laterally by the lateral movemer t of the arm 34, and through the connection38 the needle-bar will be oscillated, and the needle thereby moved laterally from the movement of said arm. And the said bell crank lever will be held from turning on its own axis bythe connection 43?, so the nee- -dle will be moved laterally a predetermined extent, and a plain zigzag st tch as in Fig. 15 will then be made. To dispose these stitches on the work so asto make the embroidered scallop shown in Fig. 21, the following adjustments are made.

The lower endof the connection 64 is adjusted a suflicient distance from the axis of the shaft 29 to actuate the pawl 63 so as toturn the ratchet wheel- 57 at the desired speed. The end of the connection 43 is adjusted out in the way 47 a sufficient extent to oscillate the bell crank lever 36" a sufficient extent on. its axis.

.It will now be understood that in the operation o'f-tlie machine the slide 53 will be reciprocated, the lever 48 oscillated, the connection 43 reciprocated, and the bell crank lever 36 oscillated, and through the connection between the same and the needle the working position of the latter will be ment of the bell crank lever 36 moves the needle laterally and the operation of said bell crank lever on its axis changes laterally. the working position of the-said laterally moving needle.

To operate the auxiliary thread carryin finger so as to loop an auxiliary threat around the links of needle thread of the said needle, the following adjustments are made.

The end of the part 73 of the connection 78 is adjusted out on the arm 75 a sufi'icient extent to give the desired oscillating movement to the rod 81, and through. it the desiredextent oflateral movement to the auxiliary thread carrying finger 91-. Then the end of the connection 69 is adjusted away from the axis of the pivot of the arm 67 a sufficient distance, to change the working position of the oscillating finger 91, laterally the extent that the working position of the needle is changed laterally. The auxiliary thread 129 is passed throu'gha usual tension device and then it is guided by usual means to, and through thread eyes 133 and 134 in the finger 91 thence to the thread-eye 97 that passes As the that runs from the same to the work, the inclined faces 98*and 99 of the nose oi the finger 91 strikes the said needle thread, and

deflects the same from the path of the finger; The oint 96 of the nose of the finger extends om the. finger. a sufficient extent to draw the auxiliary thread back of' the needle even though the work is moved a very limited extent'to each stitch. To adjust the arts so as to draw the auxiliary thread in ne with one'row of the lateral stitches thepositionof the finger is adjusted around on the rod 81, by means of the -the needle or needles.

- It will now be understood that asthe needle moves back and forth laterally the finger is moved back and forth laterally in unison with the needle, but a greater extent than the said needle, and that by said movements of these parts the auxiliary thread is looped around the links of the needle thread asper the diagrammatic view Fig. 16. If it is desired to twist the needle thread around the auxiliary thread as shown in Fig. 18, then the tension on the auxiliary thread is made strong enough relative to the tension on the needle thread to do this. i

. It is of course clear that the supply of auxiliary thread is drawnon the side of the needle that the looper moves the greater exa tent, and that sald looper thread will be loose when the looper moves in the opposite direction.'- For example, when the looper Inoves to the position shown in Fig. 11, it

will draw the supply of auxiliary thread against the tension that may be placed on the same, and this will draw the loop of auxiliary thread taut around the links of lateral stitches along this edge of the de sign. Then when the looper moves in an opposite direction to that shown in said Fig.- 11, the relation between the needle and the looper will be as indicated in Fig. 10, and in this position it will be noticed that the delivery eye of the looper is much closer to the needle, and therefore it is evident that the looper thread will not be taut, and the loop of the same will not be drawn in this direction.

In the position of the-- fpgarts asshown'in dotted'lines in Fig. 2, the

ger 91 is in the position shown in Fig. 10 and this is the position of said parts when a scallo is commenced, as at a* 2 1. As'the stitching of the scallop progresses the finger is oscillated laterally wit the needle, and the working position of the said oscillating finger is changed laterally in unison with the lateral change in the workin position of the laterally moving needle unti the connectioil 7 8 has reached the osition shown in dotted lines in Fi 2. W mm the said part has reached this oint, the stitching has reached the point 0* Fig. 21. Then during the movement of the connection 7 8 from its position in dotted lines to full lines the part of said scallop from 0* to b* is stitched, and this completes a scallop. In making this scallop the workin position of the finger 91 is changed latera y progressively with the lateral .change in the working position of the needle. When the apex 0* of the scallop has been reached the finger 91 is in the position shown in Fig. lland when the point I)* is reached it is of course back in the position shown in Fig. 10.

To guide a filling material under the links of thread of which this scallop is formed the end of the connection 110 is adjusted in the way 107 so that the finger 124 moves later ally the same extent, that the working ositions of the needle and of the auxi iary thread carrying finger 91, are changed laterally. Unlike the needle, and the auxiliary thread carrying finger 91, this finger 124 does not vibrate laterally as its position is being changed laterally. This finger 124 extends practically under the needle, so that the fill-' ing material 130 that is guided throu h the same is. delivered under the-horizontal patli of the needle, or under the link of needle thread that runs from one to another of the lateral stitches.

To make the scalloped design shown in Fig. 20 the bell crank lever is adjusted over the axis of the pivot of the arm or segment'lever 34, and the two part connection 43 is adjusted to a proper length for this purpose. With the parts so adjusted the needle will not receive any lateral movement from the action of the cam 23, but will be moved progressively laterally from the action of the cam 58, as the ratchet Wheel 57 is revolved. When this design is to be stitched theworking position of the finger 91 is adjusted so it moves an equal distance lateral y on each side of the needle and theend of the part 69 is adjusted in the way 68 so that the working position of the'said laterally moving finger will change laterally in unison with the lateral change of the needle, and the same extent that said needle changes laterally. And the end of the part isadjustedin'the way 107 of the lever 106 so that the finger 124 is 1 moved laterally also the extent that the needle is moved laterally. I a

To stitch the design shown in Fig. 22 the parts are adjusted as above, except a needle clamp is attached to the needle-har that will hold two needles.

In Figs. 12' and 13 the relation ofthe parts are shown when two needles are used, and the said two needles are moved laterally and Fig. 22 the working for passing their working positions are changed laterally to embroider a scallop over a path such as is shown in Fig. 21. To use two needles for this purpose the movement of the finger 91 relative to the movement of the finger 124 is changed to permit of the use of two needles as shown in said Figs. 12 and 13. Here it is seen that the extent of the lateral movement of the finger 124 has been slightly reduced as compared with the movement of the finger 91 as shown in Figs. 10 and 11.

In making a scallop such as is shown in position'of the finger 124 is adjusted so that it is central between the two needles, and delivers the filling material between the same.
